  2. Sagittal plane - Wikipedia

    en.wikipedia.org/wiki/Sagittal_plane

    Coronal axis, medial-lateral axis, or frontal axis is the axis perpendicular to the sagittal plane, i.e., the one formed by the intersection of the coronal and the transversal planes. [8] Extension and flexion are the movements of limbs within the sagittal plane. [9] Abduction and adduction are terms for movements of limbs within the coronal ...

  3. Anatomical plane - Wikipedia

    en.wikipedia.org/wiki/Anatomical_plane

    A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes) are parallel to it.

  4. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    The sagittal planes, also called the parasagittal planes, which are parallel to the median plane. [1] The coronal plane, also called the frontal plane, which divides the body into front and back. [2] The transverse plane, also called the axial plane or horizontal plane, which is perpendicular to the other two planes. [2]

  5. Coronal plane - Wikipedia

    en.wikipedia.org/wiki/Coronal_plane

    The coronal plane (also known as the frontal plane) is an anatomical plane that divides the body into dorsal and ventral sections. It is perpendicular to the sagittal and transverse planes. Details

  6. Anatomical terms of neuroanatomy - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_neuro...

    P: A Parasagittal plane (yellow) through one eye; parasagittal planes comprise the class of planes parallel to (and therefore lateral to) the sagittal plane. Standard anatomical planes and anatomical axes are used to describe structures in animals.

  7. Posselt's envelope of motion - Wikipedia

    en.wikipedia.org/wiki/Posselt's_Envelope_of_Motion

    The movement area of the mandible in the sagittal and horizontal planes is characteristic of the individual but varies in different persons. However, the border movement paths are reproducible in the same individual. It is suggested that the temporomandibular joints (TMJ) limit the border movements of the mandible.

  8. Anatomical terminology - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terminology

    The three anatomical planes of the body: the sagittal, transverse (or horizontal), frontal planes. Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through ...

  9. Astigmatism (optical systems) - Wikipedia

    en.wikipedia.org/wiki/Astigmatism_(optical_systems)

    The second plane used in the analysis is the sagittal plane, defined as the plane orthogonal to the tangential plane and containing the chief ray before refraction (so along the original chief ray direction). This plane intersects the optical axis at the entrance pupil of the optical system.
